A subscriber wanted to know about an old abandoned flume at Willow Creek near Hayden Hill. According to the 1938 adjudication report of Ash Creek and its tributaries had this information:
”Diversion 87 is that of the Lassen Mining Company Ditch on Willow Creek. This diversion has a low rock dam which is used to divert to the south side of Willow Creek into an earth ditch and wood box flume three-fourths mile in length. The ditch is used to transport water to a small power plant. Power is generated to pump domestic water to the Hayden Hill mine. The ditch has a capacity of 3.5 cubic feet per second which is the average available operating head during the summer months when the entire stream is diverted into the ditch.”
